We are not religious. We are not fervently atheist, more run of the mill agnostic. We do not go to church, haven't been christened, children haven't been christened.
When we talk about death to DS (4.5) we don't talk about people being in heaven. It gets talked about a fair bit in our house as 3 of his grandparents died before he was born so he often asks about them (why did they die, what happens when you die etc).
I have told him in the past that nobody really knows what happens when we die. Some people believe people go to heaven, some people believe we come back as something else and some people think nothing happens at all. I've also told him I don't really know what I believe.
Several people (who also don't go to church) have been disapproving and said that it's much easier and kinder to just stick with heaven.
What so you, oh wise ones.
